In the series, the outstanding Natalie Dormer (Margaery Tyrell in 'Game of Thrones') plays Mrs Hester Appleyard, a formidable Victorian headmistress who runs a no-nonsense school for young women in 1900s rural Australia.

The newly reworked series also stars actresses Samara Weaving, Yael Stone and many others portraying the creepy story of a school outing mystery.

Did the children simply want out from their restrictive no fun life and decide to run away? Or was there something more sinister, perhaps paranormal, at play?

Some mysteries are better left unsolved, but if it’s good enough for Stephen King to sing its praises, then he must be onto something!
